v Mn'rrron or EMBQSSING PANELS Application filed December 6,19%. Serial No. 412,222.

This invention relates to a method of em hpssing panels on cardboard, paper or the i1 re.

The principal object of the invention is to,

provide a simple and inexpensive method of producing embossed panels on sheets of cardboard )a )er or the like with the aid of an orn u n o dinary ]Ol) printing press.

Another object of the invention is to prongvide novel means for accurately positioning the male and female embossing dies in respect to each other.

Other objects will appear as the disclosure progresses. It is obvious that the actual needs of manufacture may perhaps necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated but rather to deline such limits in the appended claims. For a more general understanding of the invention attention is called to the drawings in which a preferred embodiment of the invention is illustrated. In these d 'awings like parts denote like reference characters throughout the specification.

Figure 1 is a diagrammatic sectional view of a printing press showing the male and female dies attached to the bed plate.

Figure 2 is a similar view as Figure 1 but showing the female die attached to the platen of the press.

Figure 3 is a similar view as Figure 2 but showing a sheet of stock on the platen ready to be embossed.

Figure 4 is a similar view as Figure 3 but showing the bed plate and plat-cu closed up or in the working position.

Figure 5 is a View of the bed plate of the press in the direction indicateiil by arrow A of Figure 1.

Figure 6 is a view of the finished product.

Figure 7 is a section on line 7-7 of F igure 6.

Referring now to the drawings in detail, numeral 1 designates the bed plate of an ordinary job printing press and 2 the platen. Attached to the bed plate is a plate 3 provided with series of tapped holes 4. To this so plate is fastened the male die 5 consisting of sheet metal of any desired material or shape by the screws 6. i

The female die 7 is preferably made from a sheet of cardboard having av cut out portion 8 slightly larger in size than the outside dimensions of the male die so it canfit loosely around the said die. For accurately positioning the female die 7 it is first placed around the die 5 as best shown in Figure 1 and by the aid of a very small amount of glue applied to one side of the die 7 is glued tem porarily onthe plate 3. The entire opposite surface of the said die facing the platen is then covered with glue and the platen 2 is moved towards the bed plate and then back again. The result of this is that the die 7 having more glue on the surface facing the platen than on the opposite surface will relieve itself from the plate 3 and adhere to the platen as shown in Figure 2. It will thus be seen that the female die will automatically adjust itself in the correct position without any trial or guesswork.

For the operation of embossing, the sheets are placed on the platen as shown in Figure 3 and the press operated in usual manner. Every time the bed plate and platen close up as shown in Figure t an embossed impression will be made on the card 9. Numeral 10 designates the usual stops printers use for positioning the stock on the platen. As pre viously pointed out the female die is made from cardboard or the like so that the edges will not cut the stock where it is embossed as would be the case if a steel dic were used.

It will thus be seen that I have provided a simple and efficient means of embossing panels on ordinary stock. After positioning the dies the operation is performed in the manner like printing. The plate 3 is provided with a plurality of holes so that any size male die can be attached thereto. The female die can be automatically and accurately adjusted with only one movement of the platen without any adjusting.

Having described my invention, I claim 1. In a method of positioning the component parts of a die in a printing press which consists of fastening one portion of the die to the bed plate of the press, attaching temporarily the other portion of the die to the said bed plate, moving the platen of the press towards the bed plate so that the said platen will come in contact with said 5 other portion of the die, and attaching the said other portion of the die to the said platen as the said platen moves back.

2. In a method of positioning the component parts of a die in a printing press which 1G consists of fastening one portion of the die to the bed plate of the press, adhesively attaohing the other portion of the die temporarily to the said bed plate, moving the platen of the press towards the'bed plate u so thatthe said platen will come in contact with, said other portion of the die, and adhesively attaching permanently the said other portion of the die to said platen as the said platen moves back to its original position.

In testimony whereof, I aflix my signature.

HARRY KAPLAN.
